Method Detail

getNode

public UaNode getNode(ExpandedNodeId nodeId)
               throws StatusException

Convenience method for getNode(NodeId) that takes ExpandedNodeId instead of NodeId

Throws:

StatusException

See Also:

getNode(NodeId)

getNode

public <T extends UaNode> T getNode(ExpandedNodeId nodeId,
                                    Class<T> clazz)
                             throws StatusException

Convenience method for getNode(ExpandedNodeId) that casts the result

Throws:

StatusException

See Also:

getNode(ExpandedNodeId)

getNode

public UaNode getNode(NodeId nodeId)
               throws StatusException

Convenience method for getNodeManagerTable().getNode

Throws:

StatusException

See Also:

NodeManagerTable.getNode(NodeId)

getNode

public <T extends UaNode> T getNode(NodeId nodeId,
                                    Class<T> clazz)
                             throws StatusException

Convenience method for getNode(NodeId) that casts the result

Throws:

StatusException

See Also:

getNode(NodeId)

getNodeManagerTable

public NodeManagerTable getNodeManagerTable()

Returns:

the nodeManager

getServer

public UaServer getServer()

Returns:

the server

invalidatePreviousNodeCache

public void invalidatePreviousNodeCache()

Forces the invalidation of an internal cache, which stores the last accessed UaNode, if applicable for this ServiceManagerBase. Note that normally SDK handles and calls this internally, but if an UaNode is removed without the use of SDK methods (like NodeManagerUaNode.deleteNode(NodeId, boolean, boolean)), this should be called manually.

arrayDimensionsMatch

protected boolean arrayDimensionsMatch(Variant variant,
                                       Integer valueRank,
                                       UnsignedInteger[] arrayDimensions)

Parameters:

variant -

argument -

Returns:

checkIsMethod

protected void checkIsMethod(UaNode node)
                      throws StatusException

Parameters:

node -

Throws:

StatusException

checkIsValueNode

protected void checkIsValueNode(UaNode node)
                         throws StatusException

Check if the node is a Variable or VariableType, which both implement UaValueNode.

Parameters:

node -

Throws:

StatusException

checkIsVariable

protected void checkIsVariable(UaNode node)
                        throws StatusException
